Impact of egg size on the quality of eggs, chicks, and post hatch overview of offspring during the mid stage of yield (45th week) in Hubbard broiler breeders
Background: Egg size is the most significant component in influencing the performance of the laying flock. Though commercial broiler farming is in operation, little is known about how breeder hatching egg size at mid (45 week) stage of production period affects on egg quality, chick quality and post-hatch Hubbard broiler performance.Methods: At the age of 45 weeks, hatching eggs (n=930) from a commercial broiler breeder flock were collected and classified into three egg weight categories: small (60.25±0.25g), medium (65.10 ± 0.31g), and large (70.07 ± 0.61g). These eggs more classified into 2 categories, eggs for quality parameters and eggs for incubation & posthatch performance parameters.Results: Eggs from the small egg group had a higher shell weight percentage. The shape index and specific gravity were impacted by egg size, with larger eggs having lower values. Both male and female chicks' weight and length were significantly influenced by egg size. Data of the body weight gain indicated that as broilers age, the influence of egg size on post-hatch performance of chicks’ decreases. Up until age 21, female chicks' body weight gain was highly influenced by egg size. The feed conversion ratio of female chicks at day 21 of life was considerably impacted by various egg-weight categories, while it had no effect on male and female chicks at day 35.Conclusion: Egg size favourably influenced the features of the chicks (weight and length) but had no impact on the broilers' final live body weight, feed conversion ratio, feed consumption, or mortality
Postoperative wound leak and anterior chamber reaction in patients undergoing phacoemulsification cataract surgery with sutured and sutureless corneal incisions
Purpose: To compare the rates of significant post operative wound leak and anterior chamber (AC) reaction in patients undergoing phacoemulsification cataract surgery with sutured and sutureless corneal incisions. Material and Methods: All eyes scheduled to have phacoemulsification surgery by two surgeons at two centers were selected. The first group of eyes underwent phacoemulsification surgery with 3.25 mm superior and superior-temporal clear corneal incisions. The incision was sutured using a single 10/0 nylon suture. The second group of eyes underwent an identical surgery, but the incision was not sutured. Patients were followed up at 24 hours, and 1 week and evaluated by slit lamp for wound leak (using Seidel\u27s Test) and AC cells and flare. Results: Forty eight eyes underwent surgery with sutured corneal incisions and 50 eyes underwent sutureless surgery. The mean age of patients in groups I and II were 61.2 years and 63.3 years, respectively. Following surgery, none of the patients in two groups showed wound leak at 1 day and 1 week. At the first post-op day, only 14.6% of eyes in group 1 showed AC reaction, compared to 32.0 % in group II (p = 0.04). At one week postop, 16.7% and 20.0% of eyes in Groups I and II showed AC reaction, respectively. However, the difference was not statistically significant (p = 0.67). Conclusions: The rates of postoperative wound leak and anterior chamber reaction in patients undergoing phacoemulsification cataract surgery with sutured and sutureless corneal incisions are not different. Thus sutured surgery offers no added advantages
A Study of Thermodynamic Properties of Transition Metal Diborides
AbstractThe diborides are members of a broad class of materials known as the boron-rich solids, which consist of extended networks of covalently bonded boron (B) atoms stabilized through donation of electrons from the metal atoms. Although the structures of the diborides are unique, their physical properties are somewhat similar to those of nitrides and carbides; they are extremely hard and have very high melting points. They are attractive for the same types of applications as super hard, refractory materials, such as in composites and in hard coatings. The proposal presents an overview of some of the important properties of transition metal diborides (TMB2), as these are of interest for fundamental reasons as well as for practical applications.

Effect of yeast supplementation on production parameters, egg quality characteristics and crude protein digestibility in hens
Background: Yeast (Saccharomyces cerevisiae) has a buffering effect in the digestive tract, and proper feed additives in chicken diets can improve the birds’ digestive efficiency. The present study planned with aim to investigate the effects of different levels of yeast supplementation on the egg production, egg quality traits and crude protein digestibility in hens.Methods: A total of 84 hens (40 weeks of age) were fed the dietary treatments until 50 weeks of age. The hens were distributed into 4 treatments and 3 replicates with 7 hens per experimental unit. The yeast was incorporated into basal feed with various levels (0, 0.1, 0.15 and 0.2%). The production data was obtained during trial. For determining egg quality characteristics, 30 eggs from each treatment group were used at 14-day interval of the experiment from a 2-day collection of eggs during the week. The excreta from each replicate were collected after every 2 weeks for determining the crude protein digestibility.Results: Maximum egg production and egg mass were attained from the hens provided 0.15% and 0.20% yeast supplementation. The eggshell thickness decreased with supplementation of yeast. Higher yolk weight, albumen weight, Haugh unit and grading values were observed at 0.2% level than other groups. Crude protein digestibility also improved at high levels of yeast supplementation at all ages.Conclusion: This study envisaged that yeast supplementation between 0.15 and 0.20% could be sufficient during 40 to 50 weeks of age, to augment the overall layer performance. Keywords: Baker’s yeast; feed intake; egg production; egg qualit
Visual outcome of cataract surgery.
bstract
The aim of this study was to assess whether the visual outcome of cataract surgery in the institution was in accordance with the World Health Organization recommendations. In this retrospective case series, all patients who underwent cataract surgery by a single surgeon from January 2009 till June 2011 were included. Date were collected from medical records on age, gender, visual acuity and causes of sub-optimal outcome. The main outcome was best-corrected visual acuity in the operated eye, measured 4 - 6 weeks after surgery. Data on visual outcome was grouped using WHO\u27s classification. Of the 495 eyes that underwent cataract surgery, 58% were female. Overall, 93.3% of the operated eyes had good visual outcome, while 4.4% and 2.2% had borderline and poor outcomes, respectively. Pre-existing diseases accounted for 93.9% of the borderline/poor outcome. The study showed good visual outcome of cataract surgeries performed using phacoemulsification with intraocular lens (IOL) insertion

Critical thinking is an important outcome criterion of higher education in any discipline including nursing. If nursing programs envisaged preparing graduates who are equipped with critical thinking, then the educators who plan and deliver the programs must exhibit higher level thinking in their teaching practices. This paper presents finding of the 1st phase of a National level research study that aims to assess, develop and enhance educators’ critical thinking capacity
Trend of Mortality by Water Related Intestinal infectious Diseases: A Study of National Capital Territory of Delhi, (2001 to 2011)
National Capital Territory (NCT) of Delhi is experiencing rapid urbanization for the last few decades. The area is lagging behind in water and waste management infrastructure. This is due to the fact that Delhi is recording high growth rate of population mostly through in-migration over the year which is taxing much upon the existing water resources and the provisions made for water supply. Consequently demand is higher than supply of the safe drinking water. The consumption of unsafe drinking water is therefore increasing and is causing serious health problems among the fellow residents of NCT of Delhi. These health problems are basically related to the digestive as well as excretory systems of the human body. These disorders are promoting mortality particularly among those segments of population which do not have access to potable drinking water. This paper is therefore a modest attempt towards examining the population growth rate and the scenarios of demand and supply for potable water as well as the overall water related intestinal infections and related mortality at present and their future occurrence. This requires synergy between the different sectors of the state to overcome the problem. of intestinal infection diseases in the region
Irradiation Maintains Functional Components of Dry Hot Peppers (Capsicum annuum L.) under Ambient Storage
Hot peppers used as natural flavoring and coloring agents are usually irradiated in prepacked form for decontamination. The effects of gamma radiation on the stability of functional components such as capsaicinoids and antioxidant compounds (carotenoids, ascorbic acid and total phenolics) were investigated in hot peppers (Capsicum annuum). Whole dried peppers packed in polyethylene bags were gamma irradiated at 0 (control), 2, 4, and 6 kGy and subsequently stored at 25 °C for 90 days. The irradiation dose did not substantially affect the initial contents of capsaicinoids, ascorbic acid and total phenolics, though the concentration of carotenoids declined by 8% from the control (76.9 mg/100 g) to 6 kGy radiation dose (70.7 mg/100 g). Similarly, during storage for 90 days at ambient temperature the concentrations of capsaicinoids and total phenolics remained fairly stable with mean percent reductions from 3.3% to 4.2%, while the levels of total carotenoids and ascorbic acid significantly (p < 0.05) declined by 12% and 14%, respectively. Overall, neither irradiation nor subsequent ambient storage could appreciably influence the contents of functional components in hot peppers. These results revealed that gamma irradiation up to 6 kGy can be safely used for decontamination to meet the needs for overseas markets without compromising product quality
